Abstract

PURPOSE: To provide an image forming device and a processing method therefor capable of selecting a paper sheet of which direction is optimum for staple position based on the direction of the image or a printing format, and informing an user of it when the desired paper sheet is absent. CONSTITUTION: At the time of one-side printing, the paper sheet being short in the transporting direction is selected if the image is longitudinally long (S103), and the paper sheet being long in the transporting direction is selected if the image is long laterally (S104). And, by inspecting whether the selected paper sheet has been prepared or not (S105), the printing is executed if prepared and the output paper sheet is stapled (S106), however if the selected paper sheet has not been prepared, a warning is given to the user by displaying a message calling the user's attention on a display element of a control panel, or sounding a buzzer (S107).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus having a stapling function and its processing method.

[0002]

2. Description of the Related Art Conventionally, in an image forming apparatus having a stapling function, since there is only one position where stapling is possible, stapling is performed without considering the printing direction of an image and the sheet direction.

[0003]

Therefore, in the above-mentioned conventional example, there is a problem that the desired sheet position may not be stapled without considering the sheet direction selected for the image and the front and back sides of the sheet. It was

The present invention has been made to solve the above-mentioned problems, and selects a sheet having an optimal stapling position based on an image direction or a printing format, and when there is no desired sheet, It is an object of the present invention to provide an image forming apparatus and a processing method thereof that notify that effect.

[0005]

In order to achieve the above object, the processing method of the image forming apparatus of the present invention has the following steps.

That is, in the processing method of the image forming apparatus having the stapling function, the selecting step of selecting the orientation of the paper at which the staple position is optimum based on the direction of the developed image, and the paper selected by the selecting step are selected. An image forming step of forming an image and an informing step of informing that the desired sheet is not present in the selecting step are included.

In order to achieve the above object, the image forming apparatus according to the present invention has the following structure.

That is, in the image forming apparatus having the stapling function, the selecting means for selecting the orientation of the paper having the optimum stapling position based on the direction of the developed image, and the image is formed on the paper selected by the selecting means. And an informing unit for informing that there is no desired sheet in the selecting unit.

[0009]

In such a configuration, when the orientation of the paper for which the staple position is optimum is selected based on the direction of the developed image and there is no desired paper when forming an image on the selected paper, the fact is notified. To work.

Next, the stapling operation in this embodiment will be described below with reference to the drawings.

FIG. 5 is a flow chart showing the processing procedure according to this embodiment. FIG. 6 is a diagram showing an example of stapling a vertically long image in single-sided printing, and FIG. 7 is a diagram showing an example of stapling a horizontally long image.

FIG. 8 is a diagram showing an example of stapling a vertically long image during double-sided printing, and FIG. 9 is a diagram showing an example of stapling a horizontally long image.

First, in step S101, it is checked whether single-sided printing or double-sided printing, and if it is single-sided printing, step S1.
In step 02, it is determined whether the image converted by the formatter unit 6 is a vertically long image as shown in FIG. If the image is vertically long, the process proceeds to step S103,
As shown in FIG. 6B, a sheet that is short in the transport direction is selected. If the determination result in step S102 is a horizontally long image as shown in FIG. 7A, the process proceeds to step S104, and as shown in FIG.
Select a sheet that is long in the transport direction.

Next, in step S105, it is checked whether or not the selected paper is prepared. If the selected paper is prepared, the process proceeds to step S106, the printer unit 2 is activated to perform printing, and the output paper is printed. Staple it. Also,
If the selected paper is not prepared, step S10
7, the message as shown in FIG. 10 is displayed on the display unit of the operation panel, or a buzzer sounds to warn the user.

On the other hand, in step S101 described above,
If it is double-sided printing, the process advances to step S108 to determine whether the image to be printed is a portrait image. Here, if the image is a portrait image, the process proceeds to step S109, and it is checked whether to print in order from the first page or the last page. Here, when printing is performed from the first page, the last page is at the top as shown in FIG. 8B, and therefore the process proceeds to step S104, and a sheet that is long in the transport direction is selected. Further, when printing from the last page, the first page is at the top of the sorter as shown in FIG. 8A, and therefore the process proceeds to step S103, and a sheet that is short in the transport direction is selected. .

In step S108, if the image is a horizontally long image, the process proceeds to step S110, and as shown in FIG. 9, the reverse process of the case of the vertically long image is performed.

As described above, according to the present embodiment, when a vertically long image is output and stapled at the time of single-sided printing, as shown in FIG. By printing the image with the staple position facing up, the staple position can be at the upper left of the image. Further, when outputting an image in the landscape direction and stapling, as shown in FIG. 7, by selecting a sheet that is long in the transport direction and printing the image so that the staple position is at the top, In contrast, it can be printed on the upper left.

On the other hand, in double-sided printing, when printing from the last page in order, the first page is the top on the sorter, and when printing from the first page, the first page is the bottom, By outputting as shown in FIG. 8 and FIG. 9, it becomes possible to staple at the upper left of the image.

Further, the direction of the paper used and the cassette stage for feeding the paper can be freely selected by the user, and there is no paper in the most suitable direction for stapling. In some cases you may have to choose a paper. Therefore, if stapling is instructed and it seems to be optimal for stapling, stapling is executed as it is. If not, stapling is not performed and a message on the operation screen is displayed as shown in FIG. It is displayed and asks the user whether to continue processing,
It may be possible to set in advance so that an alarm is not generated even when the staple position does not seem optimal.

Further, it may be displayed on the display screen as a message for calling the user's attention so that the relationship between the image direction, the paper direction, and the stapling position in the case of stapling in the current state can be understood.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of one device.

It goes without saying that the present invention can also be applied to the case where it is achieved by supplying a program to a system or an apparatus.

[0032]

As described above, according to the present invention,
Select the paper that has the optimum stapling position based on the image direction or print format, and if there is no desired paper, notify that fact and perform stapling at the optimum position for user convenience. It is possible to improve.
